The chemical nickel procedure - also known as electroless procedure - is applied wherever parts of complex forms need to be coated dimensionally correct and with identical contours. The X-ray amorphous chemical nickel coating boasts excellent ductility and high corrosion resistance. During the deposition is achieves a hardness of approximately 600 HV0.1. Appropriate post-curing increases the hardness (up to approximately 1000 HV0.1) and improves the wear characteristics. Because of the high phosphorus level (10.5‑12 %) the coating is non-magnetic. Further characteristics of the chemical nickel coating include its good brazeability and the compatibility when applied in the food and pharmaceutical industries. STI | Hartchrom's chemical nickel coating fulfils the requirements of DIN 50966 as well as RAL-RG 660 and the requirements of Mil-C-26074 B and AMS 2404 B. The basic material may consist if steel, stainless steel or non-ferrous metal.
Chemical nickel coatings are applied in the following areas:
- Textile industry (nozzles, thread guides)
- Electrical engineering (Shielding)
- Engineering (valves, pressure rollers, casting moulds)
- Automotive (gear wheels, clutches, gearboxes)
- Aerospace (hydraulics, pipes)
- Food and pharmaceutical industry (agitators, housings, feed screws)
